Description
LM319AMX is a version of TI/National’s LM319 high-speed voltage comparator. It compares two analog inputs and produces a digital output when one input crosses the other, enabling fast threshold detection in mixed-signal circuits. The AMX suffix indicates a specific 8-pin package variant and temperature range offered by TI.
Key points:
- High-speed voltage comparator suitable for fast threshold detection
- Typically used in zero-crossing detectors, PWM/control for power supplies, level/threshold sensing
- Package: an 8-pin variant (AMX), with exact pinout and specs found in the datasheet
Note: Exact electrical specs (propagation delay, input common-mode range, supply voltages, output type) vary by revision and package. Consult the LM319AMX datasheet for precise figures and pinout.

Equivalent
Do you want exact cross-reference equivalents across brands (drop-in replacements)? Please confirm the package (AMX suggests an 8-pin MSOP/DIP style) and required supply range. I can then provide precise part numbers from TI, Analog Devices, ON Semiconductor, etc.
Features
LM319AMX is a high-speed voltage comparator. Key features typically include:
- High-speed operation with fast propagation delay
- Single- or dual-supply operation (roughly 3V–30V common range)
- Open-collector output (requires a pull-up resistor)
- Input common-mode range extending to the negative rail (ground in single-supply use)
- TTL/CMOS-compatible input thresholds
- Low input bias/offset commonly suitable for fast switching applications
- Wide operating temperature (industrial range)
- 8-pin surface-mount package (AMX variant)
Common uses: fast level/threshold detection, zero-crossing detectors, pulse shaping, or comparators in switching circuits. For exact electrical specs (offset, bias, propagation delay, exact allowed supply, and package details) please refer to the specific LM319AMX datasheet for your revision.
